406 Engine Buildup - Part 5 (DBW)
My dad [Kork] chasing all the threads out so we get an accurate torque on the heads!

Putting the first head on..


Torqing the head down:

Second Head going on...Note the Marine Gaskets...


Look at that CNC on those heads!

Torqing the head...

Checking the Pushrod Length..




Along with the great weekend I had building my engine with Cork and Dad. I was also fortunate enough to attend my 6 yr old son's wrestling tourney, in which he won a HUGE trophy! Way to go Hunter! Not bad for his first tourney. (that's him on top)

Hope you all enjoyed the pictures. There will surely be more to follow. I plan on installing the timing cover, balancer, painting the block, etc this week. Should be ready to put in the car, in not too long.
Let hear what you think. Hopefully you enjoyed them.
:cheers: :cheers:

Those are the heads that were on my 350. Just had the shop put the K-Motion spring on.
Man I can't wait to drive this thing! I gonna be a HUGE difference, from the 350 with the rings in the shape they were.
Just out of out of curiosity. Are your heads, CNC afr or were they the older ones like Cork has that are just hand done. Any thoughts on which are/were better? Its something Cork and I have been throwing around.. you input would be interesting. :cheers:





This is gonna be an azzzkicker :yesnod:
You are going to be doing this soon... :steering:
So after all the ccing how much compression will you have?
Keep us posted.

The Best of Corvette for Corvette Enthusiasts
The anticipation has to be killin you, seeing yours go together is making my wait seem that much longer (I should get my assembled short block 1/25)
About steam holes, what exactly are you guys doing? Thanks
And yeah, please elaborate on this marine gasket.
:lurk:

This Fel-Pro performance head gasket features a PermaTorque/blue gasket body with a solid steel core to minimize torque loss and gasket blowout, and a wire ring combustion seat with stainless steel "armor" for extra sealing stress around the combustion chambers. Fel-Pro performance head gaskets are made with a pre-flattened steel wire ring, so they have the strength of wire sealing along with minimum brinelling of aluminum heads.
Apparently they are better than a regular gasket for the reason they are a little tougher because of the harsher conditions it will see with salt water (marine) applications. This is expecially important with with 400 blocks steam holes.
Someone else asked what we were doing with the steam holes for the heads. NOTHING. Corky said that in past engines when he drilled the heads out for the steam holes, he always had head gasket problems. After doing head gasket jobs several times he eventually epoxied his heads steam holes closed and he never experienced a blown head gasket again.
Also before everyone starts telling me I am gonna have an overheating problem, he is yet to experience over heating problems. My personal belief is that the overheating problem myth came about back before they had good aluminum radiators in cars.
Hope this answers some of questions.
As far as power goes I'm not real sure. I don't care if I have 500 RWHP or 350 RWHP. I just want to be a deep 11's or high 10s car.
That was a pretty open ended answer I gave, so let me further clarify. Corky is running the same EXACT internal components as me. We tried to build the two identical. He is currently running 11.10@124. Here is where the differences come in. We aren't sure if these will help me or hurt me.
1. Is the TC. I think his is a B&M 2600 or 2800 (non-lockup). Mine is a 3200 vigilante (lock-up). Corks 60' times are sub 1.5's, so either its gonna help me or hurt me, probably gonna mainly depend on traction.
2. Are the headers. His are 1 5/8" and mine are 1 3/4" Desktop dyno says I could LOOSE up to .4 with the 1 3/4 headers! But research Cork has done says differently. My personal thoughts are it should help me, but the proof is in the pudding.
3. I fully ported my SR and Manifold as you can see. I can't imagine this will do anything but help. Cork's is still in the original condition.
4. Cork's heads are the pre-cnc AFR 190/195 (That right he has one of each) :crazy: Obviously his flow pretty dang well. Mine are the more recent CNCed 190s. Again its a mystery which is better.
5. I will be custom tuning both car, so that should be a wash. He is currently running a Formato chip, but is having a few problems with timing, I think we can get ironed out and pick him up some more power.
So all in all, we both should be very near 10's next year with any luck. Corky definately will be most likely there. The neat thing about us doing this is quite a few of the upgrades I already have, Corky was thinking about doing
and if things don't work out for mine, we can pull it off his and test on mine, and vise versa. :cheers:
Anyone that has seen his car run in person, knows there is some serious power there. His first run at E-town for the last challenge, I was sitting behind him. Never saw his car run in person. He took out, on a fully prepped track with slicks and laid two black patches a good 20-25ft! Still ran an impressive 11.4sec 1/4 . I about crapped my pants! Right then I knew my efforts to build an engine with him would be well worth the time and money. :yesnod:
HP calulators for his weight car indicate he is putting out roughly 484RWHP for a car that weights 3350 lbs. That would be roughly 605 crank HP. When I had my car dynoed, and track tested. The HP calculators were within 5 hp of actual. So I would imagine he is somewere right around those numbers.
Maybe by the end of this season, if all goes well, you might even see one of us running a little juice;) Do you think that would be a little :crazy:
This should prove to be an interesting saga to follow. :thumbs:
